That's valid, but minor, really; the Class.forName(...) call is harmless.

Given how badly confused users seem to be about JDBC3 vs JDBC4 etc, I'm
reluctant to remove this until Java SE 5 is dead and gone and PgJDBC
drops JDBC4 support. Sometime around 2030 at the rate adoption of newer
releases is going.

A note to say that explicit loading is ineffective if using a JDBC4
driver and on Java 1.6 or newer would be reasonable.
